I have this stuff on the ceiling of the basement. It was expensive, but I got a deal.We live in an envelope house, which is pretty great. 16 six foot by three foot windows face South West in a solarium with a brick floor. Heat rises up to the second floor ceiling, where there are slats that distribute the heat throughout the double wall of the house. The basement is a large square with a concrete wall on one side and the other three walls are surrounded by a 5" space, and then the foundation. It's like a practice space that has double walls. Underground. I can make tons of noise.
